CCFC error signal with old/new green beam spot
I compared CCFC error signal with old/new green beam spot. The new green beam spot is upper side of camera as shown in elog2613. The old green beam spot is center of camera.
The offset of BS pointing for old/new beam spot is as follows.
| old | new | |
| pitch | 26 | 6 |
| yaw | 14 | 14 |
The attached figure shows CCFC error signal. The CCFC amplitude was 118mVpp. The new beam spot is better than old beam spot below 10Hz.
